As one of the most nurturing and protective creatures in the animal kingdom, mother cats usually take care of their kittens with great affection and devotion. However, sometimes these same mothers can display aggressive behavior towards their offspring, leaving many people wondering why mother cats attack their kittens. In this article, we will examine seven potential reasons why mother cats may attack her kittens and explore the underlying causes of this behavior.

7 Reasons why Mother Cats may attack their Kittens

One common reason why a mother cat may attack her kittens is if one of them is sick or injured. The mother may recognize that the sick kitten is weaker and may not survive, and her instincts tell her to separate it from the rest of the litter to protect them. This is common amongst kittens who are born with birth defects. The mother cat may even eat the newborn kitten if this happens.

Similarly, if a kitten has been abandoned by the mother, she may attack it to prevent it from rejoining the litter, potentially endangering the rest of her offspring.

(2) Medical Issues in the mother cat

Medical issues can also cause a mother cat to become aggressive towards her kittens. For example, if the mother is experiencing pain or discomfort, she may lash out at her kittens if they try to nurse or cuddle with her. Similarly, if the mother is suffering from an infection or illness, this may also cause her to become irritable and aggressive.

One common issue is Cat Mastitis, which causes the nipples to swell and hurt. If a kitten tries to suckle from the mother while she is in this condition, she may lash out.

Another reason why a mother cat may attack her kittens is if they are overstimulating her. Kittens are naturally curious and playful, and they may want to explore their surroundings and play with their littermates.

Just like people, cats can suffer from behavioral issues that cause them to behave abnormally. If a mother cat has a behavioral issue such as anxiety, aggression, or compulsive behavior, this may cause her to attack her kittens. In such cases, the mother cat may not be able to control her behavior, even if she wants to.

The personality and upbringing of the Mother cat also comes into play here. If the mother is irritable and grumpy by nature, she will be more prone to aggressive acts towards her kittens. Likewise, its possible she did not get the chance to socialize with other cats correctly during her upbringing. For example, if she was separated from her mother at an early age. This might result in her not knowing how to properly interact with her kittens.

Likewise, you may end up mistaking “play time” for an aggressive act. Mother cats sometimes do play-fights with their kittens. This should not be mistaken for an act of aggression. As a rule of thumb, if no claws are being used, then it’s a play-fight. Their deamoner and body posture should also be quite relaxed.

Finally, a mother cat may attack her kittens when they reach a certain age. As kittens grow older, they become more independent and may start to challenge their mother’s authority. If the mother feels that her kittens are becoming too bold or disobedient, she may become aggressive towards them as a way to assert her dominance and maintain control over the litter.

Similarly, as kittens grow older, the mother begins to distance herself from them. This is common amongst feral cats, because they will soon get pregnant again, and have to care for a new litter of kittens. Usually once the kittens are around 3 months old, the mother will begin pushing them away. She may resort to aggressive measures as well.
